1998 was the first year for the Auto 4wd, so you could drive it in 2wd, Auto 4wd (which is like 2wd, but when the rear tires start slipping it kicks the 4wd in automatically), 4wd Hi, or 4wd Lo. IT's the last of the REAL SUV's, seems like any newer and instead of having a tail-gate you'd have a hatchback. It's the SUV that was meant for some off-road use, before they started making them for use as an over-sized mini-van by soccer moms that never use the 4wd and even if they did use the 4wd only used it in snow.
